How to Properly Apply Diecut Decals with Transfer Tape: A Step-by-Step Guide from Drew’s Decals

Applying diecut decals can be a straightforward process if you follow the right steps and use the proper materials. At Drew’s Decals, we want to ensure that your decals look great and last a long time, so we’ve put together a detailed guide on how to correctly apply decals using transfer tape. Whether you’re a first-time installer or have some experience, following these steps will help you achieve a clean and professional look.

Materials You’ll Need:

  • Diecut Decal with Transfer/Application Tape
  • Isopropyl Alcohol (70-90%)
  • Lint-Free Cloth or Microfiber Towel
  • Squeegee or Credit Card
  • Masking Tape or Painter’s Tape
  • Measuring Tape (optional)
  • Hair Dryer or Heat Gun (for colder weather)

Step-by-Step Instructions

1. Prepare the Surface

Clean the Application Area:

Before applying your decal, you must clean the surface thoroughly. Any dirt, oil, or wax will prevent the decal from adhering properly and can cause bubbles or peeling over time. Here’s how:

  • Use Isopropyl Alcohol: Soak a lint-free cloth or microfiber towel with isopropyl alcohol (70-90%) and wipe down the entire area where the decal will be applied. This will remove oils, grease, and any residue left behind by cleaning products.
  • Remove All Wax: If your vehicle or surface has been waxed, it is important to remove all wax before applying the decal. Isopropyl alcohol should be sufficient, but you may need a dedicated wax remover if the wax layer is thick.

Surfaces to Avoid:

Diecut decals do not adhere well to certain surfaces. Avoid applying decals to:

  • Textured Surfaces: Decals need a smooth, even surface to bond correctly. Textured surfaces can trap air under the decal and reduce adhesion.
  • Ceramic Coated Surfaces: If your vehicle or surface has a ceramic coating, avoid applying decals without removing or bypassing the ceramic layer. Ceramic coatings can repel adhesives, leading to poor adhesion.

2. Plan Your Placement

Before peeling off the backing paper, take a moment to ensure the decal will be placed exactly where you want it.

  • Use Masking Tape or Painter’s Tape: You can use a couple of strips of masking or painter’s tape to hold the decal in place while you measure and align it.
  • Measure if Necessary: If you want to make sure the decal is perfectly centered or level, use a measuring tape to mark reference points before you begin.

3. Remove the Backing Paper

Once you’re happy with the placement, it’s time to peel off the backing paper.

  • Peel Slowly: Begin at one corner and peel the backing paper away from the decal, ensuring the decal stays adhered to the transfer/application tape.
  • Watch for Sticking: If any part of the decal starts to lift with the backing paper, press it back down firmly and slowly continue peeling.

4. Apply the Decal

With the backing paper removed, you’re ready to apply the decal.

  • Start in the Center: For large decals, start by pressing the center of the decal to the surface and work your way outward. This method helps prevent bubbles.
  • Squeegee It Down: Use a squeegee or a credit card to apply pressure, smoothing out the decal and ensuring it adheres fully. Work from the center outward to push any trapped air toward the edges. Apply firm, even pressure across the entire decal.

5. Remove the Transfer Tape

Once the decal is adhered, it’s time to remove the transfer tape.

  • Peel Slowly at an Angle: Begin peeling the transfer tape back slowly at a 45-degree angle. Go slowly and check as you peel to ensure that the decal remains in place.
  • Watch for Lifting: If any part of the decal lifts with the transfer tape, press it back down with the squeegee and try peeling again.

6. Final Touches

After removing the transfer tape, go over the decal with the squeegee one more time to ensure all edges are firmly stuck down. If you see any small bubbles, gently press them out toward the nearest edge.

Ideal Temperature for Decal Application

The temperature of both the surface and the surrounding environment is crucial for proper decal application. Here are the recommended temperature guidelines:

  • Optimal Temperature: The best temperature for applying decals is between 50°F (10°C) and 90°F (32°C). Decals adhere best in this temperature range.
  • Cold Weather Considerations: If you’re applying the decal in cooler temperatures (below 50°F), use a hairdryer or heat gun to gently warm up both the surface and the decal before applying. Heat helps the adhesive activate and adhere properly.
  • Hot Weather Considerations: Avoid applying decals in extremely hot temperatures or direct sunlight (above 90°F), as the adhesive may become too soft, making it difficult to position the decal without it stretching or warping.

Additional Tips for a Perfect Application

  • Avoid Touching the Adhesive: Try not to touch the sticky side of the decal when peeling the backing paper, as oils from your fingers can affect adhesion.
  • Let the Decal Cure: After applying the decal, give it 24-48 hours to fully bond with the surface. Avoid washing the surface or exposing it to extreme conditions during this period.
  • Care for Your Decal: After installation, regular washing and care will keep your decal looking great for years. Avoid harsh chemicals and always hand wash if possible.

Common Application Mistakes to Avoid

  • Skipping Surface Prep: Not cleaning the surface thoroughly or applying to a dirty or waxed area will result in poor adhesion and a short lifespan for the decal.
  • Applying to Textured or Ceramic Coated Surfaces: These surfaces are not ideal for decals and can lead to early peeling or improper adhesion.
  • Ignoring Temperature Guidelines: Applying a decal when it’s too cold or too hot can ruin the application. Always check the temperature before starting.

Conclusion

Applying a diecut decal with transfer tape may seem like a delicate process, but following these detailed steps will make the job much easier. Remember, surface preparation is key—clean thoroughly with isopropyl alcohol, remove all wax, and avoid textured or ceramic-coated surfaces. Be patient during the process, and you’ll end up with a professional-looking decal that lasts for years.
